Tips for Solving Sudoku

Is it true? Are there any tips for solving the now famous numbers game? Some folks say that you don’t have to have any tips and that math skills are not needed, however this line of thinking has recently been up for debate.

Tips are a dime a dozen, as with any popular game, the most touted is Ariadne’s thread which was the first depth-first search algorithm of its kind to help solve the puzzle. Experts say that it can solve or prove invalid any Sudoku puzzle. Others, however, say that it is inefficient.

Another Sudoku trick is also the most elementary strategy for solving the puzzle. This tip is to examine each cell and list all its possibilities. Figure out what all of the numbers are that have not ruled out by a conflict with another section and when you find a section that has only one allowed, number write it in. If you employ a smaller writing within the cells you can feasibly write in at least three possibilities within the corners of the cell. This is generally the way it is done.

Another method is to write down all the cells within a row, a column or a block where a certain number can appear. If there is a number that can be put in only one position then that’s your number. These are two ways that you can weed out a number as a candidate within other areas.

There are some that subscribe to the idea that Sudoku can be solved by nothing more than repeating either of these tips but then again if it were that easy, the game probably wouldn’t have lasted as long as it has. There are so many possible variations of the game that although this might work for one or two times, it would not work for all of the versions of Sudoku.
Another, more complicated tip to solving Sudoku is to use pairs of cells within a row, column or block. The logic of this Sudoku trick is that when two such cells have only two possible values, those values are excluded everywhere else. This is more complicated way to look at it but it apparently has worked for some.

There are probably as many tips out there as there are players, these are just a few. The truth of the matte is this, there is apparently 6,670,903,752,021,072,936,960 possible games of Sudoku out there and there are probably just as many personalized tips from player all over the world.
